The PBP was released before a major update to shotguns was applied. Before the update, only one bullet was able to hit someone. Damage per bullet was reduced to counter the new change, but it's entirely possible that the gun is still overpowered. So it's definitely a good idea to try some changes to it.

Yes, players may have bought it only because it's so powerful. However, iEra's currency is not a real form of legal tender, and we reserve the right to change the game as we see fit. The changes we make are for the benefit of the majority of players. If you feel you are entitled to an overpowered weapon just because you bought it while it was overpowered, I'm sorry, but it's not possible. Refunds cannot be given either.

I wish we could always release things in a balanced way, but unfortunately for everyone, we are volunteers, not paid professional game devs. We make mistakes, and we hate messing up the game just as much as you hate it when we do that.
